TUBULAR LANTERN.

Application filed November 29,

To all whont it may concern: j

Be it known that I, ALBERT R. Pnrrormno, j a citizen of the UnitedStates, and a resident i of Rochester, in the county of Monroe and IState of New York, have invented certain new and useful Improvements inTubular i Lanterns, of which the following is a specification. 1

This invention relates to tubular lanterns; and it consists in themechanism hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of a lantern embodyingthis invention. Fig. 2 is a detailed view of the separated wires formingpart of the globe-holder. Fig. 3 is a perspective view of the lever-liftfor the globe. Fig. 4 is a perspective view of a modified form of saidleverlift. Fig. 5 is a side view showing the lantern-bail in itsdepressed position, and Fig. 6 is an enlarged cross-section on thebottom line 6 of Fig. 1.

In the drawings, 1 is the usual oil-font. 2 is the air chamber orgallery, and 3 is the burner-cone. The chamber or gallery 2 is connectedwith the lower ends of the side tubes 4 4, which are also, if desired,soldered or fastened to the font 1. The upper ends of the side tubesextend, as shown in dotted lines, into side openings in the vertical orcanopy tube 5. The canopy-tube has side ribs 6 6, whereby the two partsof the tube may be fastened together and which also constitute means forpreventing rotary movement of the canopy 7 upon the canopy-tube 5. Aglobe-plate 8 is adapted to rest upon the burner-cone 3 when the lanternparts are in their normal positions. The canopy 7 has a rolled edge 8,in which the ends 9 and 10 of the side wires 11 and 12 are fastened.Each side wire has a lower curved portion 13 14, which rests in therolled edge 15 of the perforated globe-plate 8. A loop or finger-piece16 may project from one of the lower ends, such as 14, of a side wire.Each side wire has an outwardly-projecting bend 17, whose sides areobtuse angles, and a depression 18, whose sides are also obtuse angles.Each a notch 20, (see Fig. 6,) in which the adjacent side wire restswith a little pressure in order to insure contact. When the lanternparts are in their normal position, (shown in Fig. 1,) the projections19 rest on the upper sides of the projections 17 of the side wires, andthus hold the globe 21 and its connected parts down in place on theburner-cone l).

I/Vhen the globe-plate is lifted, the canopy 7 slides upon thecanopy-tube 5 and the side wires 11 and 12 move along the projections 20until the said projections rest in the depressions 18 in the side wiresand hold the globe and its connected parts in their upper position inorder to give access to the burnercone and lower part of the lantern.The depression 18 in the side wires may be long, as shown in Fig. 1, ormay be abrupt, as shown in Fig. 2. \Vhcn the globe is again lowered toits normal position and the projections 19 pass the summit of theproject-ions 17, the s ring of the side wires tends to force the gfobeand globe-plate intoplace, and the pressure of the side wires againstthe rigid projection holds these parts in their normal position.

By the employment of the notched pro'ec tions 19 and of the canopy 7 andglobc-piate 8, having the rigidly-attached side wires 11 and 12, theglobe-frame, consisting of the canopy, the globe-plate, the globe-wires,and the usual globe spring attached to the canopy, may be manufacturedcomplete and then inserted into the lantern-frame, consisting of theoil-pot, gallery, air-tubes carrying the notched projections 19, and thecanopytube, by the simple process of sliding the canopy on thecanopy-tube and compressing the side wires 11 and 12 until they snapinto the notches 20 in the projections 19, whereupon the parts areassembled. This ability to manufacture the lantern-frame and theglobe-frame each complete and separately is an important result andcannot be obtained without the open notches in the guide projections 19.

The rigid projections 19 may be formed of wire, in which case the freeends 23 of a single piece of wire pass through holes in the side tube 11or 12, and a portion 2-1 of said wire lies against the face or side ofthe side tube 4, so that when solder is applied to the parts theprojection 19 will have a long bearing against the side tube, and theprojection 19 is firmly held in position. So, too, the guard-wires 25have portions 26 at their ends bent at right angles to the plane of themain portion of the guard-wire, so as to lie against the face or side ofthe side tube and terminal portions 27, projecting through holes in theside tubes. \lVhen solderis applied to the side tubes, the adjacentportions of the guard-wires are held most firmly in position.

The lever-lift apparatus has a bearing 28 on one of the side tubes,which may, as shown, form an axis at right angles to the plane of theside tube. In this bearing turns the lever 29, having the handle end 30and the operating end 31, the latter of which is, as shown, parallel tothe axis of the bearing 28. The operating end 31 may have upon it a loopof any suitable form passing around the short horizontal portion 32 ofone of the side wires, so that as the lever is tilted in one directionit will raise the globe-plate and its connected parts and when tilted inthe other direction will lower said globe-plate and its connected parts.In Fig. 3 the loop mentioned is a loop 33, formed of a separate piece ofWire having its ends 34 turned around the operating end 31 and inclosingor spanning the horizontal portion 32 of the side wire. The loop 33 isadapted to swing upon the operating end 31, so that as the lever israised and lowered the loop swings and there is little lost motion. Itis, however, possible, by making a large loop 35,'Fig. 4, integral withthe operating end 31, to reduce the number of parts.

The handle or bail 36 is made of a single piece of wire, as usual, whoseends 37 project through perforations in the outer sides of the upperends of the vertical side tubes. It is common to break globes byallowing the handle to fall and strike the globe. In order to preventthis, the bail 36 close to each terminal portion 37 has an inward sharpbend 38, which is adapted to strike the side tube before the bail 36 canstrike the globe 21. (See Fig. 5.)

What I claim is 1. In a globe-frame for tubular lanterns, a canopyhaving a rolled edge, a globe-plate having a rolled edge, and two sidewires, each having a vertical portion, and end portions turned at anangle to the vertical portion, one end portion of each side wire beinginclosed in the rolled edge of the canopy, the other end portion beinginclosed in the rolled edge of the globe-plate, whereby the globe-plateand the canopy are held rigidly in position in combination with alantern-frame, and guides thereon for said side wires having opennotches for said side wires.

2. In a globe-frame for tubular lanterns, a canopy having a rolled edge,a globe-plate having a rolled edge, and two side wires, each having avertical portion, and end portions turned in opposite directions and atan angle to the vertical portion, one end portion being inclosed in therolled edge of the canopy and the other end portion being inclosed inthe rolled edge of the globe-plate, whereby the globe-plate and thecanopy are held rigidly in position in combination with a lantern-frame,and guides thereon for said side Wires having open notches for said sidewires.

3. In a tubular lantern having side tubes, a rigid projection on a sidetube, a globe-frame having the usual vertical side wires, one of whichhas a depression and a long gradual outwardly-projecting portion andadjacent to the upper end thereof a short steep inwardlyprojectingportion for engagement with said rigid projection, 'whereby theglobe-frame is held downward by the engagement of said steepinwardly-projecting portion with said rigid projection and the upwardmovement of the globe-frame is made smooth and easy by the pressure ofsaid long and gradual portion against said rigid projection and is heldin the raised position by engagement of said projection in saiddepression.

4.. In a tubular lantern having side tubes, a rigid projection on a sidetube, a globe-frame having the usual vertical side wires, one of whichhas a depression and a long gradual outwardly-projecting portion andadjacent to the upper end thereof a short steep inwardly-projectingportion for engagement with said rigid projection, whereby theglobeframe is held downward by the engagement of said steepinwardly-proj ecting portion with said'rigid projection and the upwardmovement of the globe-frame is made smooth and easy by the pressure ofsaid long and gradual portion against said rigid projection and is heldin the raised position by engagement of said projection in saiddepression, and a lifting-lever pivoted on one of the side tubes andhaving a loop around one of said side wires.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
